Using the local HMI

At delivery, logging on is not required and the user has full access until users and passwords are
created with PCM600 and written into the IED or Centralized Account Management is enabled.
Commands, changing parameter values and resetting indications, for example, are actions requiring
password when the password protection is activated. Reading information on the LHMI is always
allowed without password.

Using the HMI

Utility security policies and practical consideration should always be taken on the
feasibility of using passwords. In emergency situations, the use of passwords could delay
urgent actions. On the other hand when security issues must be met, the two factors
must be seriously considered.
Do not switch off the auxiliary power supply to the IED before changes, for example,
setting parameter or local/remote control state changes are saved.
